Blood tests showed increased C-reactive protein (CRP) levels (343 mg/L, normal < 6 mg/L), predominantly lymphocytic leukocytosis (68.9 × 109/L) with a known baseline around 45 × 109/L due to his CLL, elevated lactate level (3.6 mmol/L, normal < 1.6 mmol/L), hyperglycemia (10.3 mmol/L), mildly elevated liver enzymes (aspartate aminotransferase 105 U/l, normal < 51 U/l; alanine aminotransferase 110 U/l, normal 35 to 50 U/l), coagulopathy (international normalized ratio 1.3, normal 0.9 to 1.2), and mild macrocytic anemia (hemoglobin 11.6 g/dL, normal 14.0 to 17.5 g/dl). The gene discussed is CRP; the disease is macrocytic anemia.
